The Amish are American, you childish ignoramus. They came from Germany hundreds of years ago. Now they are here in The Promised Land practicing Christianity the way they see fit. Europe and the Netherlands are now a Godless waste land soon to be subject to Sharia Law.

In 2010 the Dutch population was made up of 16,615,000 people. Among these 24.6% (4.1 million) were Roman Catholics, 14.8% (2.5 million) were Protestants (of these 2.25 million or 13.5% were Reformed and Lutherans, 230,000 or 1.3% were other Protestants), 0.7% (130,000) were other Christians, Orthodox, Jehovah's Witnesses and others, 5.8%
